The letter suggests a meeting with the mayor and his transport advisors to discuss a range of possible solutions for improve the service at the Chiswick tube station.

Councillor Andrew Dakers said: "When I first ran for Parliament in 2005 the issue of poor service at Turnham Green tube was one of the key local concerns raised with me by Chiswick residents.

"Five years on and the problem remains unsolved by the incumbent labour MP or by Transport for London."

Some solutions to the "inadequate" service that campaigners are asking to be considered include extending the early morning and late evening stops at the station in Turnham Green Terrace and moving the Piccadilly line stop from one station, such as Barons Court, to Turnham Green.

Councillor Dakers said: "The population increase in Hounslow is above the London average because of the many new housing developments in the area.

"That is why there is a real need to improve the tube network. This will help Chiswick residents in both Hounslow and Ealing boroughs.

The line currently only stops between 5.28am and 6.45am in the morning and 10.30pm to 12.48am at night – and despite 40 years of lobbying for an all-day tube stop, residents have had no success.

"What we need are face-to-face conversations with the people who make the decisions so that we can unpack the issues and find solutions.

"If a genie gave me three wishes, I would use one of them to get the Piccadilly line to serve Turnham Green throughout the day."
